Reconstruction of a multimode entangled state using a two-photon phase-sensitive linear amplifier
(American Physical Society, 2003)
We propose a model for the measurement of an arbitrary multimode entangled state of the cavity field using two-photon correlated emission laser. We consider two cases: (a) The modes have different frequencies and are ...
Influence of pump-phase fluctuations on entanglement generation using a correlated spontaneous-emission laser
(American Physical Society, 2007)
In this paper, we study the effect of phase fluctuations of the pump field upon the entanglement generation in a two-photon correlated emission laser (CEL). We consider initial vacuum and coherent state for the two-cavity ...
Entangled radiation via a Raman-driven quantum-beat laser
(American Physical Society, 2009)
We propose a scheme for the entanglement generation of two cavity modes using a four-level Raman-driven quantum-beat laser (QBL). The atomic coherence is generated by a Raman-type two-photon process. Two different sufficient ...
Two-mode single-atom laser as a source of entangled light RID A-5077-2009
(American Physical Society, 2007)
A two-mode single-atom laser is considered, with the aim of generating entanglement in macroscopic light. Two transitions in the four-level gain medium atom independently interact with the two cavity modes, while two other ...
Entanglement generation in a two-mode quantum beat laser RID A-4660-2010
(American Physical Society, 2007)
We analyze the quantum correlations between side modes of a quantum beat laser when a two-level atomic medium is driven strongly by a classical field. The squeezing and the entanglement generation of the cavity radiation ...
Spectral narrowing via quantum coherence
(American Physical Society, 2006)
We have studied the transmission through an optically thick Rb-87 vapor that is illuminated by monochromatic and noise-broadened laser fields in Lambda configuration. The spectral width of the beat signal between the two ...
Proposal for direct measurement of concurrence via visibility in a cavity QED system
(American Physical Society, 2008)
An experimental scheme is proposed that allows direct measurement of the concurrence of a two-qubit cavity system. It is based on the cavity-QED technology using atoms as flying qubits and relies on the identity of the ...
Quenching of spontaneous emission through interference of incoherent pump processes
(American Physical Society, 2003)
We investigate the steady-state spontaneous emission of a V-type three-level atom, with the coherence between the two upper levels modified and controlled via incoherent pumping to a fourth auxiliary level. The external ...
Quantum teleportation of an arbitrary superposition of atomic Dicke states
(American Physical Society, 2005)
We propose a scheme for teleporting an arbitrary superposition of entangled Dicke states of any number of atoms (qubits) between two distant cavities. Our method relies on adiabatic passage using multi-atom dark states in ...
Manipulation of the Raman process via incoherent pump, tunable intensity, and phase control
(American Physical Society, 2008)
We present a proposal to manipulate the Raman process via incoherent pump, tunable intensity, and phase control of the driving fields. It is found that Raman absorptive peaks can become Raman gain peaks by controlling the ...
